zsh
iterm
最近 IT 不知道搞什么鬼，公司的 MBP 中的默认 shell 总是被修改为 bash，今天测试了一下，刚改完不到 10 分钟就又退回 zsh 了

Go to iTerm2 -> Preferences -> Profiles -> Default and in the General Tab set the Command to /bin/zsh ( or maybe /usr/local/bin/zsh ) instead of Login shell.

今天发现使用这种方法启动的 zsh 在 PATH 设置上会又区别，比如缺少/usr/local/bin，然后就调用不到使用 brew 安装的 neovim 了
这是使用 iterm 使用 zsh 直接打开新的 tab 页面
➜ ~ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/Users/devin.chenyang/opt/arcanist/bin/:/usr/local/opt/fzf/bin
这是使用ch来切换 shell
➜ ~ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:/Users/devin.chenyang/opt/arcanist/bin/:/usr/local/opt/fzf/bin
可能跟 Open Directory server 有关系 https://apple.stackexchange.com/a/88279
